That is, the NFC communication device 12 transmits a request signal to the surroundings at regular intervals according to the NFC standard, and receives the response signal transmitted from the NFC communication device 52 of the mobile device 50 in response to the request signal. When the NFC communication device 12 receives the response signal, the NFC communication device 12 demodulates the authentication data (ID information) included in the response signal and outputs it to the wireless controller 16.

The BLE communication device 14 is a communication device that wirelessly communicates with the mobile device 50 by using a communication method according to the BLE communication standard. The BLE communication device 14 also operates by receiving power supplied from the battery 26, and performs BLE communication with the BLE communication device 54 of the mobile device 50 through an antenna (not shown). The communicable range of BLE communication is several meters or more, which is wider than the communicable range of NFC communication (about 10 cm).

The BLE communication device 14 also executes polling for detecting the portable device 50 according to the instruction from the wireless controller 16. That is, the BLE communication device 14 transmits a request signal to the surroundings at regular intervals according to the BLE communication standard, and receives the response signal transmitted from the BLE communication device 54 of the mobile device 50 in response to the request signal. .. When the BLE communication device 14 receives the response signal, it demodulates the authentication data (ID information) included in the response signal and outputs it to the wireless controller 16.

The wireless controller 16 includes a processing device (not shown) and a memory 18, and controls the NFC communication device 12 and the BLE communication device 14. Specifically, when a predetermined polling condition is satisfied, the wireless controller 16 outputs a command instructing the BLE communication device 14 having a wide communicable range among the NFC communication device 12 and the BLE communication device 14 to execute polling (). Polling process).

Further, when the wireless controller 16 receives the ID information received and demodulated by the BLE communication device 14, the wireless controller 16 collates the ID information with the ID information stored in the memory 18 (authentication processing). Then, when the matching of the ID information is confirmed as a result of the collation, the authentication of the mobile device 50 is completed. As a result, the certified portable device 50 can be used to operate the door lock device 22 (unlock the door for getting on and off), start the engine (not shown), and the like. The ID information stored in the memory 18 may be stored in the memory (not shown) of the vehicle control device 20, or may be stored in each of the NFC communication device 12 and the BLE communication device 14. good.

Further, in the wireless controller 16, communication between the BLE communication devices 14 and 54 is established when the BLE communication device 14 receives a response signal from the mobile device 50 (hereinafter, this communication establishment is also referred to as "BLE connection"). When the authentication of the mobile device 50 is completed by the response signal, a command for instructing the NFC communication device 12 to execute polling is output. That is, in the wireless communication system according to the present embodiment, polling by the BLE communication device 14 starts when a predetermined polling condition is satisfied, and polling by the NFC communication device 12 starts when the BLE connection and authentication are completed. This point will be described in detail later.

Then, when the NFC communication device 12 receives the response signal transmitted from the NFC communication device 52 from the mobile device 50 in response to the polling by the NFC communication device 12 (hereinafter, the NFC communication device 12 receives the response signal). The establishment of communication between the NFC communication devices 12 and 52 is also referred to as "NFC connection"), and it is assumed that the door lock device 22 has been unlocked using the portable device 50. Switches to the unlocked state.

The vehicle 10 further includes a vehicle control device 20, a door lock device 22, and a battery 26. The door lock device 22 is configured to switch the door for getting on and off of the vehicle 10 between a locked state (locked state) and an unlocked state (unlocked state).

The vehicle control device 20 includes a CPU (Central Processing Unit), a memory, a signal input / output port, and the like (none of them are shown). The vehicle control device 20 controls the vehicle 10 in various ways. As an example, when the vehicle control device 20 receives a notification from the wireless controller 16 that the authentication of the mobile device 50 is completed, the vehicle control device 20 permits the operation of the door lock device 22 (door unlocking). Then, the vehicle control device 20 outputs an unlock command (unlock command) to the door lock device 22 according to the unlock request of the door for getting on and off, and a lock command (lock command) to the door lock device 22 according to the lock request of the door for getting on and off. ) Is output.

The battery 26 is an auxiliary battery of the vehicle 10, and is composed of, for example, a lead storage battery. The battery 26 supplies operating power to the NFC communication device 12, the BLE communication device 14, the wireless controller 16, and the vehicle control device 20.

The portable device 50 includes an NFC communication device 52, a BLE communication device 54, a control device 56, an input device 62, a display device 64, and a battery 66.

The NFC communication device 52 is a communication device that wirelessly communicates with the vehicle 10 by using a communication method according to the NFC standard. The NFC communication device 52 performs NFC communication with the NFC communication device 12 of the vehicle 10 through an antenna (not shown). The NFC communication device 52 includes a passive tag (IC tag) that is operated by radio waves from the NFC communication device 12. That is, the NFC communication device 52 operates by the radio wave received from the NFC communication device 12 without receiving the power supply from the battery 66. Therefore, the NFC communication device 52 can communicate with the NFC communication device 12 of the vehicle 10 even when the power of the mobile device 50 is turned off.

Upon receiving the request signal emitted from the NFC communication device 12, the NFC communication device 52 generates and modulates a response signal including ID information unique to the mobile device 50 written in the passive tag (IC tag) to the vehicle. It is transmitted to 10 NFC communication devices 12.

The BLE communication device 54 is a communication device that wirelessly communicates with the vehicle 10 by using a communication method according to the BLE communication standard. The BLE communication device 54 operates by receiving electric power from the battery 66, and performs BLE communication with the BLE communication device 14 of the vehicle 10 through an antenna (not shown).

When the BLE communication device 54 receives the request signal emitted from the BLE communication device 14, the BLE communication device 54 acquires the ID information unique to the mobile device 50 from the memory 60 of the control device 56. Then, the BLE communication device 54 generates and modulates a response signal including the acquired ID information, and transmits the response signal to the BLE communication device 14 of the vehicle 10.

The control device 56 includes a CPU 58, a memory 60, a signal input / output port (not shown), and the like. The control device 56 controls the mobile device 50 in various ways. As an example, the control device 56 reads the ID information of the portable device 50 stored in the memory 60 from the memory 60 and outputs the ID information to the BLE communication device 54 in accordance with the request from the BLE communication device 54.

The input device 62 is a device that receives various input operations of the user to the mobile device 50, and is, for example, a touch sensor that detects a touch operation on the display device 64 and various operation buttons provided on the mobile device 50. The display device 64 displays various information of the mobile device 50, information corresponding to an input operation from the input device 62, and the like. The input device 62 and the display device 64 may be integrally configured by a touch panel sensor.

The battery 66 is a rechargeable and dischargeable secondary battery, and is composed of, for example, a lithium ion secondary battery. The battery 66 can be charged by an external power source using a charging device (not shown). Then, the battery 66 supplies the operating power to the BLE communication device 54, the control device 56, the input device 62, and the display device 64.

As described above, the NFC communication device 52 is configured to include a passive tag that operates by radio waves from the NFC communication device 12, and therefore does not receive power from the battery 66.

In the above wireless communication system, NFC communication between NFC communication devices 12 and 52 and BLE communication between BLE communication devices 14 and 54 are possible. Regarding NFC communication and BLE communication, as shown in FIG. 2, the communicable range of BLE communication is wider than the communicable range of NFC communication. On the other hand, BLE communication is impossible because the operating power is not supplied from the battery 66 to the BLE communication device 54 when the power of the mobile device 50 is turned off, but NFC communication does not require the power supply from the battery 66. Since it is a passive type, communication is possible regardless of the power state of the mobile device 50.

In this wireless communication system, when the authentication of the mobile device 50 is completed through BLE communication, the door lock device 22 can be locked / unlocked by performing an operation such as touching a sensor provided on the door knob. Further, in the wireless communication system according to this embodiment, in addition to the above operation, the door lock device 22 can be operated by using the portable device 50. Specifically, the door lock device 22 can be locked / unlocked by holding the mobile device 50 over a predetermined position where the NFC communication device 12 is provided in the vehicle 10 to form an NFC connection.

In both NFC communication and BLE communication, in order to detect that the user who owns the mobile device 50 approaches the vehicle 10, the NFC communication device 12 and the BLE communication device 14 of the vehicle 10 detect the mobile device 50. Polling is done. During polling, radio waves (request signals) are output to the surroundings at regular intervals in order to detect the mobile device 50 approaching the vehicle 10, so that a dark current flows. If the dark current associated with this polling is large, problems such as the battery 26 being unintentionally exhausted may occur.

Therefore, in the wireless communication system according to the present embodiment, when the establishment of BLE communication (BLE connection) and the authentication of the mobile device 50 are completed, the wireless controller 16 starts polling by the NFC communication device 12. Since the communicable range of BLE communication is wider than the communicable range of NFC communication, the NFC connection is not performed before the BLE connection. Therefore, in the present embodiment, polling by the NFC communication device 12 is started when the BLE connection is completed. This makes it possible to reduce the dark current due to polling before the BLE connection is completed.

Polling by the NFC communication device 12 (hereinafter referred to as "NFC polling", whereas polling by the BLE communication device 14 may be referred to as "BLE polling") is when a predetermined NFC polling stop condition is satisfied. Is stopped at. The NFC polling stop conditions are, for example, when the BLE connection is cut off, when the boarding of the user is confirmed, when the ignition key or the like is turned on to enter the Ready-ON state, or when the vehicle 10 starts running. Etc. can be established.

FIG. 3 is a timing chart showing an example of polling by the BLE communication device 14 and the NFC communication device 12 of the vehicle 10. With reference to FIG. 3, the polling condition is satisfied at the time t0, and the request signal is transmitted from the BLE communication device 14 toward the surroundings (BLE polling).

The polling condition can be satisfied, for example, when the ignition key or the like is turned off to enter the Ready-OFF state, and the passenger gets off and the door is locked. Even before the time t0, the request signal is transmitted at regular intervals after the polling condition is satisfied.

At time t1, the response signal transmitted from the BLE communication device 54 of the portable device 50 in response to the request signal transmitted from the BLE communication device 14 is received by the BLE communication device 14, and the radio between the BLE communication devices 14 and 54 is received. Connection (BLE connection) is completed. Although not particularly shown, when the response signal from the BLE communication device 54 is received by the BLE communication device 14, the ID information included in the response signal is collated and the mobile device 50 is authenticated. ..

When the BLE connection and the authentication of the mobile device 50 are completed, the wireless controller 16 outputs a polling start command to the NFC communication device 12, and the NFC polling starts. When the NFC polling is started, the user of the vehicle 10 releases the door lock device 22 by holding the mobile device 50 over the predetermined position where the NFC communication device 12 is provided in the vehicle 10 to form an NFC connection. It can be switched to the locked state (unlocked state). Then, according to the wireless communication system according to this embodiment, the NFC polling is stopped until the BLE connection is completed, so that the dark current due to the polling can be reduced.

FIG. 4 is a flowchart showing an example of a processing procedure executed by the wireless controller 16 of the vehicle 10. The series of processes shown in this flowchart are repeatedly executed at predetermined intervals.

With reference to FIG. 4, the wireless controller 16 determines whether or not the polling condition for the BLE communication device 14 to execute polling is satisfied (step S10). The polling condition can be satisfied, for example, when the vehicle 10 is in the Ready-OFF state and the door is locked after the passenger gets off the vehicle. If the polling condition is not satisfied (NO in step S10), the process shifts to return.

When it is determined in step S10 that the polling condition is satisfied (YES in step S10), the wireless controller 16 outputs a command instructing the BLE communication device 14 to execute polling (step S20). As a result, the BLE communication device 14 transmits a request signal to the surroundings at regular intervals.

Next, the wireless controller 16 determines whether or not communication is established between the BLE communication devices 14 and 54 (BLE connection) and the authentication of the mobile device 50 is completed through the BLE communication (step S30). Specifically, the response signal transmitted from the BLE communication device 54 of the mobile device 50 in response to the request signal from the BLE communication device 14 is received by the BLE communication device 14, and the ID information included in the response signal is collated. Based on the result, it is determined whether or not the authentication of the portable device 50 is completed.

Then, when it is determined in step S30 that the BLE connection and the authentication of the mobile device 50 are completed (YES in step S30), the wireless controller 16 outputs a command instructing the NFC communication device 12 to execute polling. (Step S40). That is, the NFC polling starts when the BLE connection and the authentication of the mobile device 50 are completed.

Next, the wireless controller 16 determines whether or not there is a request to unlock the door lock device 22 (step S50). Specifically, in the wireless controller 16, whether the communication is established between the NFC communication devices 12 and 52 by the user holding the mobile device 50 over the predetermined position where the NFC communication device 12 is provided in the vehicle 10. That is, it is confirmed whether the NFC connection is formed, and when the NFC connection is confirmed, it is determined that the unlocking of the door lock device 22 is requested.

Then, when it is determined in step S50 that the door lock device 22 has been requested to be unlocked (YES in step S50), the wireless controller 16 instructs the vehicle control device 20 to unlock the boarding door. , The door lock device 22 is switched to the unlocked state (step S60). Although not shown in particular, the door lock device 22 can be switched to the unlocked state by the user performing an operation such as touching a sensor provided on the door knob.

If the BLE connection and authentication are not completed in step S30 (NO in step S30), or if there is no unlock request for the door lock device 22 in step S50 (NO in step S50), the process shifts to return. Will be done.

As described above, in the present embodiment, when the communication between the BLE communication devices 14 and 54 having a relatively long communicable distance is established and the BLE connection is completed, the polling by the NFC communication device 12 is started. .. Therefore, according to the present embodiment, it is possible to reduce the dark current due to polling before the BLE connection by the BLE communication devices 14 and 54 is completed.

Further, according to the present embodiment, as an operation of switching the door lock device 22 to the unlocked state, in addition to an operation such as a user touching a sensor provided on the door knob, the portable device 50 is placed at a predetermined position of the vehicle 10. Since it is also possible to hold it over, the options for unlocking the door will increase and convenience will improve.

[Modification example]
In the above embodiment, the NFC polling is started when the BLE connection and the authentication of the mobile device 50 are completed. However, regardless of the authentication on the BLE side, the NFC polling is started when the BLE connection is completed. You may. In this case, the NFC side may perform the authentication.

FIG. 5 is a flowchart showing an example of a processing procedure executed by the wireless controller 16 in this modified example. The series of processes shown in this flowchart are also repeatedly executed at predetermined intervals.

With reference to FIG. 5, the processes of steps S110 and S120 are the same as the processes of steps S10 and S20 shown in FIG. 4, respectively. Then, in this modification, when the BLE polling is executed in step S120, the wireless controller 16 determines whether or not the communication is established between the BLE communication devices 14 and 54, that is, whether or not the BLE connection is formed. (Step S130). Specifically, when a response signal is transmitted from the BLE communication device 54 of the mobile device 50 in response to the request signal from the BLE communication device 14 and the response signal is received by the BLE communication device 14, a BLE connection is formed. It is judged that it is a Bluetooth.

When it is determined in step S130 that the BLE connection has been formed (YES in step S130), the wireless controller 16 outputs a command instructing the NFC communication device 12 to execute polling (step S140). That is, in this modification, NFC polling starts only when the BLE connection is formed.

Next, the wireless controller 16 determines whether or not communication is established between the NFC communication devices 12 and 52 (NFC connection) and the authentication of the mobile device 50 is completed through the NFC communication (step S150). Specifically, the response signal transmitted from the NFC communication device 52 of the mobile device 50 in response to the request signal from the NFC communication device 12 is received by the NFC communication device 12, and the ID information included in the response signal is collated. Based on the result, it is determined whether or not the authentication of the mobile device 50 is completed.

Then, when it is determined in step S150 that the NFC connection and the authentication of the mobile device 50 have been completed (YES in step S150), the wireless controller 16 determines whether or not there is a request to unlock the door lock device 22. Determine (step S160). For example, when the user holds the mobile device 50 at a predetermined position where the NFC communication device 12 is provided in the vehicle 10 and the communication between the NFC communication devices 12 and 52 continues for a predetermined time or longer, the wireless controller 16 may be used. It is determined that the door lock device 22 has been requested to be unlocked.

Then, when it is determined in step S160 that the door lock device 22 has been requested to be unlocked (YES in step S160), the wireless controller 16 instructs the vehicle control device 20 to unlock the boarding door. , The door lock device 22 is switched to the unlocked state (step S170). Although not particularly shown, after the authentication of the mobile device 50 is completed in step S150 (YES in step S150), the door lock device 22 can also be operated by the user touching the sensor provided on the doorknob. Can be switched to the unlocked state.

If the BLE connection is not formed in step S130 (NO in step S130), the NFC connection and the authentication of the mobile device 50 are not completed in step S150 (NO in step S150), or the door lock is performed in step S160. If there is no unlock request for the device 22 (NO in step S160), the process shifts to return.

The same effect as that of the above-described embodiment can be obtained by this modification.
In the above-described embodiment and modification, the NFC communication device 52 is mounted on the mobile device 50, but the NFC communication device 52 is a card or the like that does not have a power supply and is different from the mobile device 50. It may be mounted on.

Further, in the above-described embodiment and modification, in the vehicle 10, the wireless controller 16 is provided separately from the vehicle control device 20, but the vehicle control device 20 may have the function of the wireless controller 16. ..

Further, in the above-described embodiment and modification, instead of the BLE communication devices 14 and 54, a UWB communication device that performs wireless communication using a communication method that conforms to an ultra wide band (UWB) communication standard is used. It may be provided for both the vehicle 10 and the portable device 50. Further, in addition to the BLE communication devices 14 and 54, the UWB communication device may be provided in both the vehicle 10 and the portable device 50.

Further, in the above-described embodiment and modification, the NFC communication device 12, the BLE communication device 14, and the wireless controller 16 are mounted on the vehicle 10, but the range of the present disclosure is mounted on the vehicle. It is not limited to wireless communication devices. For example, the NFC communication device 12, the BLE communication device 14, and the wireless controller 16 may be provided in the house or the delivery box, and the portable device 50 may be used as a key for unlocking the door of the house or the delivery box.
